Pathfinder - Challengers of the Lost Continent

Details

Centuries ago the land of Belvuel vanished overnight leaving thousands of miles of swirling vortices in the ocean. Each vortex spewed forth a strange black mist that twisted the flesh of the foolish sailors who ventured too near. A decade ago Belvuel returned as suddenly as it vanished. In the intervening years few expeditions ventured to the lost land and even fewer returned. Those who have returned tell stories of cult nations, pretender kings, and ruined spire dungeons a thousand feet tall, strange twisted ruins that emanate alien magics, and dark scarred forests that seem to bleed strange black mists that twist the flesh and transforms people into undead abominations. They also speak of glittering treasures, amazing magics, and untold glories for those mighty enough to win them.

This Game uses a home brew setting with the standard Pathfinder rules. I have the Super Genius Games "Adventurer's Handbook" and the "Northlands" book by Kobold Press, so I am lenient on third party content if it's designed for Pathfinder.
